A distributed tracing Akka extension based on Zipkin, which can be used as performance diagnostics and debugging tool.
It allows you to:
- trace call hierarchies inside an actor system;
- debug request processing pipelines (you can log to traces, annotate them with custom key-value pairs);
- see dependencies between derived requests and their contribution to resulting response time;
- find and analyse slowest requests in your system.
Distributed tracing approach used by Zipkin synergise with akka-remote and akka-cluster. Extension provides integration with Play framework and Spray toolkit.
See wiki for more information.
The best way is to use project's activator templates: general features, Scala and Java API, Spray integration, Play integration. Also, you can read tracing overview page.
